What is bacterial conjugation? A. Bacterial conjugation is a method by which bacteria communicate with each other to coordinate group behaviour.B. Bacterial conjugation is a process where bacteria absorb DNA from their surrounding environment for genetic transformation.C. Bacterial conjugation is a process where bacteria exchange genetic material (DNA) through a direct physical connection, leading to … Read more

What does bacterial growth on a plate containing a particular trait (such as antibiotic resistance) after a bacterial conjugation experiment indicate? A. The bacterial colonies have acquired the trait from the F- strain (recipient). B. The bacterial colonies have resisted the trait and not undergone conjugation. C. The bacterial colonies have undergone mutation and developed … Read more

What is bacterial conjugation and how does it play a role in antibiotic resistance? A. Bacterial conjugation is a method by which bacteria exchange genes. If a bacterium develops resistance to an antibiotic, it can quickly share this resistance with other bacteria through conjugation. This would happen if a bacterium evolves or acquires a Resistance … Read more

What must occur for bacterial conjugation to take place? A. The cells must transfer RNA. B. One of the cells must be E. coli. C. The cells must come into contact with each other. D. Each cell must contain a plasmid.

True or False: Can two different species of bacteria conduct bacterial conjugation? Responses True, as long as they have identical chromosomal DNA. True, as long as they have identical chromosomal DNA. True, as long as there is a plasmid to be transferred between them any bacteria can do it. True, as long as there is … Read more

True or False: For conjugation to occur, bacterial cells must physically contact each other. A True B False

Which of the following statements about conjugation is true? A Transferring DNA between cells in conjugation requires a virus carrier. B The donor and recipient cell must be in direct contact (touching) to transfer DNA. C Conjugation can only occur between bacteria of the same species. D Conjugation can occur with or without a conjugative … Read more
